!     SLRR_MIN - Minimum RR value allowed for grid cell random roughness (mm)
!     SLRR_MAX - Maximum RR value allowed for grid cell random roughness (mm)
!     WZZO_MIN - Minimum wwzo value allowed for grid cell bare, non-ridged, surface aerodynamic roughness (mm)
!                (currently this corresponds to ~1.67mm RR)
!     WZZO_MAX - Maximum wwzo value allowed for grid cell bare, non-ridged, surface aerodynamic roughness (mm)
!                (currently this corresponds to ~100mm RR)

!     SURF_UPD_FLG - value = 0, surface updating is disabled
!                    value = 1, surface updating is enabled
